a wire delivers 12.0 c of charge in 4.0 s. what is the current in the wire?\n3.0 a\n8.0 a\n16 a\n48 a

Explanation:

Step1: Recall current - charge formula

The formula for current $I$ is $I=\frac{Q}{t}$, where $Q$ is the charge and $t$ is the time.

Step2: Substitute given values

Given $Q = 12.0\ C$ and $t=4.0\ s$. Substitute into the formula: $I=\frac{12.0\ C}{4.0\ s}$.

Step3: Calculate the current

$I = 3.0\ A$.

Answer:

A. 3.0 A
